The Barthel Index (BI) cannot be used to measure initial stroke severity or by extension, to stratify patients by severity in acute stroke trials because most patients are bedbound in the first few hours after stroke, either by their deficit or by medical directive. Our objectives were to clarify the threshold of acute BI for use in the prediction of subsequent independence in activities of daily living (ADL) and to assist in the definition of acute stroke rehabilitation goals. Subjects comprised 78 patients out of 191 inpatients admitted with acute stroke at our hospital during 2006-2007. The BI ADL score was divided into 2 ranges (BI> or =60 and < or =40), in a process similar to previous studies. During the acute period (from onset to approximately 3 weeks), all patients with a BI> or =40 could improve their ADL in 6 months. Patients with a BI< or =40 exhibited two ADL recovery outcomes (improved and no change) at 6 months. We also found that the skill level of basic activities related to standing was significant indicator of BI improvement (P<0.001). BI scores determined at approximately 3 weeks were reliable predictors of ADL disabilities at 6 months.
The objective of this study was to examine the possibility of predicting the long-term outcome of severe stroke patients from the ADL status at discharge. The design is a retrospective observational study in the stroke center at Tokushima University Hospital. Severe stroke patients at discharge with Barthel Index (BI) scores ≤ 40 (N=51) were divided into two subgroups retrospectively, improved and unimproved. The Functional Independence Measure (FIM) and BI were analyzed at discharge, 3 and 6 months after onset. Correlation analysis between BI and FIM showed good correlation, especially between BI and motor FIM (mFIM). In conclusion, the ADL status at discharge from a stroke center is not definitely indicative of the long-term outcome, although good recovery of severe stroke cases was observed in males and younger patients, and in patients with motor FIM score>25. This result shows that the first 3 months after the attack should be regarded as an important time window for intensive rehabilitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
